Salvia plant named ‘DSALRS203’

ABSTRACT

A new and distinct  Salvia  cultivar named ‘DSALRS203’ is disclosed, characterized by early flowering, compact plant habit, large flowers and short flowering stems. The new variety is a  Salvia,  normally produced as an outdoor garden or container plant.

Latin name of the genus and species Salvia sylvestris.

Variety denomination: ‘DSALRS203’.

BACKGROUND OF THE INVENTION

The new Salvia cultivar is a product of a planned breeding program conducted by the inventor, Gavriel Danziger, in Moshav Mishmar Hashiva, Israel. The objective of the breeding program was to produce new Salvia varieties for ornamental commercial applications. The open pollination resulting in this new variety was made during April of 2007.

The seed parent is the unpatented, proprietary seedling variety referred to as Salvia sylvestris ‘SAN-Z-1’ The pollen parent is unknown as it was an open pollination breeding program. The new variety was discovered in August of 2008 by the inventor in a group of seedlings resulting from the 2007 open pollination, in a research greenhouse in Moshav Mishmar Hashiva, Israel.

Asexual reproduction of the new cultivar was performed by vegetative cuttings. This was first performed at a research greenhouse in Moshav Mishmar Hashiva, Israel during November of 2008 and has shown that the unique features of this cultivar are stable and reproduced true to type in about 70 successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘DSALRS203’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘DSALRS203’ These characteristics in combination distinguish ‘DSALRS203’ as a new and distinct Salvia cultivar:

-   -   1. Compact habit.     -   2. Large flowers     -   3. Short flowering stems.     -   4. Early flowering.

Plants of the new cultivar ‘DSALRS203’ are similar to plants of the seed parent, Salvia sylvestris ‘SAN-Z-1’ in most horticultural characteristics, however, plants of the new cultivar ‘DSALRS203’ differs in the following:

-   -   1. More compact plant.     -   2. Earlier flowering.     -   3. Shorter flowering stems.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘DSALRS203’ are comparable to the unpatented commercial variety Salvia ‘May Night’. The two Salvia varieties are similar in most horticultural characteristics; however, the new variety ‘DSALRS203’ differs in the following:

-   -   1. Comparison variety height is 30-45 cm, whereas candidate         variety is 25-30 cm.     -   2. Comparison variety spread is 30-35 cm, whereas the candidate         variety is 20-30 cm.     -   3. Candidate variety begins blooming earlier in the Spring, by         approximately 1 month.

Plants of the new cultivar ‘DSALRS203’ are also comparable to the unpatented commercial variety Salvia ‘Snowhill’. The two Salvia varieties are similar in most horticultural characteristics; however, the new variety ‘DSALRS203’ differs in the following ways:

-   -   1. Comparison variety has mounded growth habit whereas candidate         variety has upright growth habit.     -   2. Comparison variety has white flowers whereas candidate         variety has purple flowers.     -   3. Comparison variety spread is 30-40 cm, whereas the candidate         variety is 20-30 cm.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘DSALRS203’ grown in a greenhouse, in a 13 cm pot. Age of the plant photographed is approximately 3 months old from rooted cutting.

FIG. 2 illustrates a close up of the inflorescence.

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
